Background: Rates of prenatal alcohol use in Sub-Saharan Africa (SSA) are increasing despite regulatory bodies urging pregnant women to abstain from alcohol. Tanzania has minimal policies, interventions, and educational programs addressing prenatal alcohol exposure. Consequently, a considerable number of mothers and their fetuses are exposed to alcohol, leading to serious health consequences like fetal alcohol spectrum disorder (FASD).

Acute Q fever diagnosis via paired serology is problematic because it requires follow-up for convalescent sample collection; as such, it cannot provide a diagnosis to inform a treatment decision at the time of acute presentation. Real-time polymerase chain reaction (PCR) may be a useful approach for the diagnosis of acute Q fever in endemic settings. Among febrile patients enrolled in a sentinel surveillance study for Q fever at two referral hospitals in Moshi, Tanzania, from 2012 to 2014, we analyzed those with paired sera for IgG to Coxiella burnetii (C.

Introduction: Women with HIV (WHIV) have higher risks of adverse pregnancy outcomes, particularly in the absence of antiretroviral treatment(ART), and timing of ART may impact risk.

Methods: In IMPAACT 2010 (VESTED), 643 pregnant WHIV in 9 countries were randomized 1:1:1 to initiate ART: dolutegravir (DTG)+emtricitabine(FTC)/tenofovir alafenamide(TAF); DTG+FTC/tenofovir disoproxil fumarate (TDF) or efavirenz (EFV)/FTC/TDF. We describe adverse pregnancy outcomes in women with a subsequent pregnancy during 50 weeks of postpartum follow-up: spontaneous abortion (<20 weeks), stillbirth (≥20 weeks), preterm delivery (<37 weeks) and small-for-gestational-age (SGA).

The increased prevalence of non-communicable diseases (NCDs) in recent years has led many Low- and Middle-Income Countries (LMICs), including Tanzania, to develop policies to manage their burden. Musculoskeletal (MSK) conditions, such as arthritis, account for 20% of all years lived with disability in LMICs, but the NCD strategies rarely address them. There is substantial research on the disruption MSK conditions cause to people's lives within High-Income Countries, but very little is known about the lived experiences in LMICs.

Article Synopsis
  • The study investigated risk factors for spotted fever group rickettsioses (SFGR) in the Kilimanjaro Region, Tanzania, focusing on febrile patients from local hospitals between 2012 and 2014.
  • Of 1,190 participants, 54.6% had SFGR exposure, with 9.2% displaying acute SFGR; factors such as age, rural living, and temperature were significant in determining risk.
  • The findings highlight that children under 2 years, rural residents, and those in cooler areas may be at higher risk for SFGR, suggesting a need for targeted prevention strategies and additional research on tick exposure.

Qualitative research methods are central to understanding many public health problems. However, capacity building for qualitative research is globally skewed toward high-income countries, with a significant skills deficit in low- and middle-income countries (LMICs). To address this imbalance and provide a model program, we developed the Qualitative Research Leaders (QRL) program, a pipeline program to increase qualitative research capacity in LMIC institutions and foster leadership in qualitative research.

Article Synopsis
  • The study highlights the serious threat of antibacterial resistance (ABR) in low-resource areas like East Africa, specifically focusing on multi-drug resistant urinary tract infections (MDR UTIs).
  • Researchers examined a variety of factors, including behavioral, environmental, socioeconomic, and demographic influences, that contribute to the risk of developing MDR UTIs among outpatients in Kenya, Tanzania, and Uganda.
  • Findings suggest that individuals at higher risk tend to have multiple social and environmental disadvantages, indicating that effective interventions should consider these intersecting factors rather than just focusing on antibiotic use alone.
